Ian Anderson is mostly credited with inventing the flute with which he performed with an old bum guy known as Aqualung in a band known as Jethro Tull, who was the lead singer and a former agriculterist. Incidentally, he created the flute by accident, while attempting to invent the seed drill with Tull, the flute was an unfortunate unsucessful first attempt. However, it led Anderson to become a member of a great classic rock band.
